RAILWAY-SWITCH MECHANISM.

Application fiIed May 27, 1912.

To all whom it may concern Be it known that I, MARTIN D. GARNER, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma,- have invented certain new and useful Railway-Switch Mechanisms, of which the following is a specification, reference being had to the accompanying drawings.

This invention has reference to the art of railway switches, and more particularly to those switches in the art, adapted to be operated by mechanism situated remotely from the switch, and which is adapted to be operated at will, by mechanism earned by a car.

It is an object of the invention to automatically throw a switch by mechanism carriedby a car.

Another object is to give a new and desirable construction, by which friction 1s reduced and by which the casual operation of the switch is guarded against.

These and other slnnlarly important'objects of the invention becoming more apparent from a further reading of this specification, may be obtained through suitable forms of mechanism embodying'the invention, and one of such forms is illustrated on the drawings accompanying and forming a part of this specification, whereon,

Figure 1 is a plan view of a portion of railway, showing a switch, and the invention applied to throw the same. Fig. 2 illustrates a plan view of means adapted to cooperate with mechanism, carried by a car, for operating the switch. Fig. 8 illustrates a similar view, of means for acting in conjunction with the switch, and adapted to cooperate with the means illustrated in Fig. 2. Fig. 4 illustrates a side elevation of a car; a portion of the switch throwing means, and means carried by the car for cooperating with the switch throwing means. Fig. 5 illustrates, perspectively, a form of means carried by the car, for throwing the switchoperating means.

The rails 6, ties 7, and switch-tongues 8, are, of course, of the usualtype, constituting no new invention. Carried by a suitably located pivot bearing 9, preferably remote from the tongues 8, and which may be located in a suitable framing, such, for instance. as 10, which may be located between the rails 6, there is a lever 11, adapted to be moved about a pivot 9, there connected to,

the switch-tongues 8 through connecting rods 12, and 13, in any suitable manner, for instance, by having the rods 12 and 13 piv oted, as at 14, to the lever 11 and as at 15 to ears borne by the switch-tongues. Preterably superimposed upon the lever 11, and occupying the same pivot 9, is a bell-crank, comprising arms 16, 17 and 18, the longer one 16 of which is adapted to be retained in one or'theother of its operative positions, by

j a suitable form of locking means, which, in

the present instance, may comprise a keeper 19, pivoted on the face of the lever 11, as at 20, and provided with bills 21 and 22, each of which, in season, and alternately, will engage with stops 23 and 24, thusre taining the switch-tongue throwing mechanism in one or another of its operative positions. This keeper 19, may be associated with the lever 11, in any suitable manner,

and in the present instance is provided with arms 25 inserted slidably, in an eye 26; borne 'at the extremity of the lever 11 and open on the outer end of this lever to receive the arm 25. The bills 21 and 22 are also adapt- -ed and arranged to move along a cam face 27 while "stress is'being imparted to either of'the arms '17, or 18, of the bell-crank, when the thrust will be distributed through the pivot 9, the pivot 20, and to the bills on the keeper 19, which, at the time, is bearing against the cam-face 27, and thus will the lever 11 be thrown, in one direction or an- .other, to operate the switch tongue 8 to an assembled and borne in this framing. These 7 cables 28 and 29, respectively, after passing about guides 32 and 38, are connected to the arms 34 and 35 of a spider, that is borne on a pivot 36, suitablv located, for instance, in a framing 37, which is located between the rails 6, and remotely from the mechanism previously described. This spider, in-

eludes an arm 38, which bears a trip 89, in the present instance, in theform of a roller,

borne on a stud which projects through I aslot 40, in the framing 37, and which-willbe engaged by switch throwing amechanism,:- carried by the car, for operating the switch.

' This spider also includes an arm 41, to which is connected, as at 42, a bar 48, adapted to reciprocate in abearingr44, as the spider throws from one position to another, during, its operation, and for the purpose ofinsuring a complete throw of thisspider, a spring; 45, convoluted about the bar 48,willexert its force between the extremity of arm 41 and the bearing 44.

For the purpose of operating the mechanism, so far set forth any suitable form of mechanism may be adopted, and one of such forms, comprehendsa pair of racks 46 and 47, adapted to operate in guides 48 and 49 mounted onsupports 50 adapted to be secured to the bolsters 51. ofthe car, and which are steadied by braces 52. To the lower extremities of these racks46 and 47, respectively, aresecured shoes or cams 53 and 54, which are adapted: to be shifted at will alternately into the path. *ofthe element 89 in the framing 37. For? the purposeof operating. this rack 46 'andiraclc47 and the? cams 53 and 54, bell-cranks.55,connectedto the rackstby connecting rods s56, are mount ed on abearing. rod 57 journaled in. bear ings 58, carried by the car, bolsters 51. Onearm of each crankis connected to cables-59 and 60 which passover rollers 61, borne by the bolsters, and the'cables are connected to. an arm 62 of bellcranks which are pivoted as at 63 to bearings 64, carried at the fore end of the car, and with which belllcranks' arms 65 are associated which bear footepieces 66 anda67s For thepurpose of normally ver pivoted commonly With the first lever having an arm extended overthefirst named lever and provided with a socket open on \the outer end of the arm,-a keeper pivoted on the first lever outwardly ofthe arm and having; an arm inserted slidably'in the socket, bills formed onathe keeper projectedt saliently from the keeper, a cam member outwardly of therfirst lever. having" a face concentric of the lever and disposed to receive the bills coincidently and slida'bly thereagainst atgits intermediate part, the cam terminating in shoulders for engagement, with the bills at opposite limits of: the movement vof the first: lever to prevent casual. return thereof, and

means to operate the secondlever:
